From poisonous mussel, BIMKCKI: (III., 79) obtains! an 

 aurochloridc of a base crystallizing in needles. The quan- 

 tity isolated was insufficient for analysis. It is interesting 

 Ixtause of its property of inducing salivation, a symptom 

 which has been observed by SCIIMIDTMAN.N and by URUMPE 

 in some cases of mussel poisoning. 



A BASE was obtained by GUA I;KS< IN and Mosso (Jouni. 

 fiir praktitche Chem., 28, 508) from fresh beef, in the 

 alkaline etlicr extract obtained by DRAGENDORFF'fl method. 

 It formed a yellowish alkaline fluid, of unpleasant odor, 

 and after a time gave a deposit of microscopic crystals. 

 The hydrochloride gave the following reactions : Gold chlo- 

 ride, yellow crystalline precipitate ; platinum chloride, pre- 

 cipitate ; potassium iodide and iodine in hydriodic acid, 

 kermes-red precipitate ; phosphotungstic acid, nothing ; 

 phosphomolybdic acid, an abundant yellow precipitate; tan- 

 nic acid, heavy, grayish precipitate, same with MAYEU'S 

 reagent ; picric acid, yellow precipitate; MAUMK'S reagent, 

 precipitate soluble in excess ; potassium bichromate, noth- 

 ing ; potassium permanganate and sulphuric acid, violet 

 color ; potassium ferricyauide and ferric chloride, Prussian 

 blue precipitate. 



By giving a precipitate with tannin, and not with phos- 

 photungstic acid, it resembles neurine. 



CH. ( Ji; AM has studied the decomposition of yeast under 

 the influence of an infusion of hay. The yeast was allowed 

 to putrefy for fourteen days, and was then treated with zinc 

 sulphate. The latter was precipitated by barium hydrate, 

 and the filtrate after the removal of the barium by sul- 

 phuric acid, was evaporated to dryness, and extracted with 

 al tsolute alcohol. The alcoholic solution was evaporated, 

 and the residue again extracted with alcohol. The extrac- 

 tion residue was taken up with water, and again subjected to 

 t he alxwc treatment with xinr sulphate, barium hydrate, etc.
